Organizational system evolution

In ancient times, Inner Mongolia was already the distribution range of Yangshao culture. See also Hongshan Culture unearthed in Liaohe River. Before the Spring and Autumn Period and the Warring States Period, some northern nomadic people, such as Xiongnu and Donghu, lived a nomadic life in Inner Mongolia.

Historical records record that Xia Jie's son Chunwei is the ancestor of Xiongnu, and generally introduce the history of Xiongnu for more than 1000 years after Chunwei fled to the north.
